hi everyone…im currently working on an image which i already convert it in terms of its gray level values for pixel by pixel…right now i have problem in accessing the values of those arrays….for example, an image containing 70rows (i=70) and 70columns (j=70)….let say i want to read one whole row first..but i want to read it 5 values at a time, end then the next 5, and then the next until the end…how do i do that???the reason i want to read it bit by bit is because i want to find the average of each 5 gray level values and run a statistical analysis on those averages…
I=imread('1.jpg');D=double(I(:,:,1));[i,j]=size(D);n=0;k=1;grayval(1)=0;for i=25:40 for j=1:40 glevel(j)=D(i,j) grayval(k+1)=grayval(k)+glevel(j) n=n+1; k=k+1; end xbar(i)=grayval(k)/nend
there's something wrong with my code…it returns the average of the whole j…can u please help me??tanx in advance…
